Footings
Footings for chimneys with fireplaces should be provided as described on [page 7]; for chimneys without fireplaces, the footings should rest on good firm soil.
Figure 34.—A typical fireplace, illustrating practical details of construction. An alternate method of supporting the hearth is shown in the lower right-hand corner. The various letters refer to specific features discussed in the text.
Hearth
The hearth should be about flush with the floor, for sweepings may then be brushed into the fireplace. When there is a basement, an ash dump located in the hearth near the back of the fireplace is convenient. The dump consists of a metal frame about 5 by 8 inches in size, with a plate, generally pivoted, through which ashes can be dropped into a pit below ([fig. 35]).
Figure 35.—The ash-pit should be of tight masonry and should be provided with a tightly fitting iron clean-out door and frame about 10 by 12 inches in size. A clean-out for the furnace flue as shown is sometimes provided.
